The SR 3/US 41 at SR 53 intersection in Calhoun, Ga., is a critical juncture
because of the high volume of through traffic and turns. During peak periods,
855 vehicles per hour make southbound left turns, causing considerable delays
at the signal. A $34 million continuous-flow intersection for the northbound
and southbound approaches relocates left turns to a signalized median opening
upstream of the intersection.

Communicating this innovative design solution in a visual format was crucial
to achieve approval from the Georgia DOT. Bentley Descartes allowed the
designers to create plots with high-resolution color photography of the project
area, and the team used MicroStation to overlay the technical design on the
photography to display the proposed improvements.

Bentley MX provided tools to achieve interoperability and ROI for the design modelingprocess, utilized during public consultations through visualization andautomated construction activities of plant and machinery.
